I sent you a lab several weeks ago and have not gotten an reply. Also, I sent you and email about a week ago and have not heard from you.

If you have submitted a lab and it hasn't been posted, you should submit another copy.

If you don't have a copy and you submitted the backup form, I should be able to locate it if I know when it was submitted and which lab it was.

Even if you didn't submit the backup form, it should be possible to locate it if I have the information.
